Appearing on ITV’s This Morning today, his sister Abra recalled the family’s panic that Troy wouldn’t pull through his initial surgery and how he’s now getting stronger every day.

She also spoke about the huge positive reaction to a photo of Troy in his hospital bed and how the well wishes from around the world had put a smile back on his face.

Talking about the night of the fire, she said: “He got himself out of bed on fire, out the front door just as the fire brigade was arriving. He was rushed straight to hospital [and then transferred to a specialist burns unit at another hospital.]

"We all went straight there and they prepared us for the worst, saying he probably wouldn’t make it out of theatre.”

“It felt like days,” she continued. “It was about 12 hours all together until he was out of theatre and they said he was stabilised.”

Abra and her mother were the first to enter Troy’s hospital room and see him.

“It was absolutely horrific,” said Abra. “I’ve never witnessed anything like it in my life. Just looking at him like that, it was unimaginable and really hard.”

Four days later things took a turn for the worse and the family were warned Troy only had hours to live and they should start saying their goodbyes.

Abra, however, says the family refused to believe that was it.

“Everyone was there and they said he probably had three hours left at the most,” she said. “We just couldn’t accept it and couldn’t believe what they were saying.

"It had been four days [since the fire]. We all went in and we didn’t say goodbye; we said we would see him later as we had faith in him being a fighter, but it was really hard.”

After being given just three hours to live, defiant Troy pulled through and, after spending 14 weeks in intensive care, he was moved to another ward.

He now has a 99 per cent chance of survival.

Then, Troy asked Abra and their brother Kyle to take a photo of him in his hospital bed and post it to social media.

“He said out of the blue to take a picture of him and post it to social media,” said Abra. “We looked at him and said, ‘Are you sure?’ He said yeah so we went okay, and it’s gone viral.”

Abra said the reaction to the photo had been incredible for Troy, boosting his confidence after the ordeal.

“It’s massively built his confidence up and made him really happy. He’s been smiling a lot this week and can’t believe it. It’s had over 10,000 likes and he didn’t expect even a few. He’s had messages from all over the world.”

“As a 19 year old lad, it’s a massive, life-changing situation,” she added. “I think he was worried… he told me when he does come home he would hardly want to go out of the house as he thinks people might stare at him and make fun.”

Looking to the future, Troy needs to learn to walk again and use his hands again. His sister said the family are taking “one day at a time” and looking forward to welcoming him home.

She acknowledged Troy will need continued treatment and support once he leaves hospital, so a Go Fund Me page has been set up to help pay for the cost of that.

Friends, family and complete strangers have nominated the 19-year-old for a Mirror Pride of Britain award to recognise his incredible courage in the face of his appalling injuries.

Abra thanked the thousands of people who have sent message of support - and told how the nomination for a Mirror award had lifted his spirts.

"We were shocked even though he definitely deserves it," she said.

"Troy is going to be buzzing. We were really worried about upsetting people with the picture, we know it's a shock.

"But that is my Troy - a true fighter".

Durham Police and the fire service launched an investigation into the cause of the fire, which has yet to be established.

It is feared the fire started by two candles which were lit upstairs before Troy went to bed, and then set light to the various boxes used to carry his grandmother's belongings to her new home when she moved in.
